Problems solved by technology

Firstly, this method greatly increases the overall control time of the fan; secondly, this method calculates the fan PWM value only through the CPU temperature, without considering other factors, which is too simplistic; thirdly, this method controls the fan of the entire cabinet as a whole, and cannot be controlled by each fan. The temperature sensor of the node determines the fan speed required by the node, which cannot achieve the purpose of energy saving

Embodiment 1

[0019] A high-efficiency and energy-saving SmartRack cabinet fan control method. The method installs the fan speed control table in the BMC processing chip of each server node of the SmartRack cabinet, and determines the required temperature of the node by the temperature sensor (sensor) installed on each server node. speed of the fan.

Embodiment 2

[0021] Such as figure 1 As shown, on the basis of Embodiment 1, the specific implementation process of the method described in this embodiment is as follows: the SmartRack cabinet is provided with multiple RBP management modules, each management module is responsible for its corresponding 4 server nodes, and the BMC of each server node will Calculate the obtained air intake temperature, CPU core temperature, memory temperature, PCH temperature and VR temperature data with the fan speed control table embedded in the BMC to determine the final fan speed PWM, and send the PWM to its corresponding RBP The management module and the RBP module take the maximum value of the corresponding four fan speed signals, and transmit the maximum value to the corresponding fan window, thereby realizing an efficient and energy-saving fan control method.

Embodiment 3

[0023] Such as figure 2 As shown, on the basis of embodiment 1 or 2, the method operation steps described in this embodiment are as follows:

[0024] 1) The BMC of the server node calculates the acquired air intake temperature, CPU core temperature, memory temperature, PCH temperature and VR temperature data with the fan speed control table embedded in the BMC to determine the final fan speed PWM;

[0025] 2) The server node transmits the PWM to its corresponding RBP management module;

[0026] 3) The RBP module takes the maximum value of the 4 fan speed signals, and transmits the maximum value to the corresponding fan window.

[0027] In this way, the SmartRack cabinet installs the fan speed control table in the BMC processing chip of each server node, and the temperature sensor of each server node determines the fan speed required by the node, which avoids repeated adjustment of the fans in the entire cabinet and greatly saves The calculation time of the fan speed PWM and...

Abstract

The invention discloses an efficient and energy-saving method for adjusting and controlling fans of a SmartRack cabinet. The method includes the steps that fan rotating speed control meters are installed in BMC processing chips of server nodes of the SmartRack cabinet, and the fan rotating speeds required by the nodes are determined through temperature sensors arranged at the server nodes. The fan rotating speeds required by the nodes are determined through the various temperature sensors of the nodes of the SmartRack cabinet, the fans are directly adjusted and controlled through RBP modules, and the whole fan adjusting and control time is fundamentally saved; PWM of the fans is calculated according to the various temperature sensors, and adjusting and control are more accurate accordingly; and the fans are adjusted and controlled according to temperature information of the fans, and therefore energy consumption is reduced. By means of the method, the fans of the SmartRack cabinet are more conveniently, more flexibly and more safely adjusted and controlled, and the cooling requirements of the nodes of the SmartRack cabinet are guaranteed to the maximum degree.

Description

technical field [0001] The invention relates to the technical field of software and hardware adjustment and heat dissipation control, in particular to an efficient and energy-saving SmartRack cabinet fan adjustment method. Background technique [0002] Compared with traditional rack and blade servers, SmartRack server is an innovative form of server, which breaks the design idea of ​​traditional servers, takes standard racks as the design unit, and integrates heat dissipation, power supply modules, and management of traditional servers. The modules are concentrated as the unified power supply, fan wall and management module of the rack, and the traditional server is only used as the computing module of the rack. This product is not only the computing and storage module of the cloud data center, but also the only way for the evolution of the traditional data center to the cloud computing data center. . [0003] SmartRack is a new type of high-density rack-type server develop...
